GSS Graphic Size Selection: Establishes the height and width for the
Current Font Definition.
Source: Application
Destination: Level 3
Format
CSI Pn SP C
Description
Select Pn as follows:
Pn Meaning
0 Sets height to 100 decipoints.
n Sets height to Pn units.
The unit size depends on the Select Size Unit (SSU) command setting.
Positioning Unit Mode (PUM) has no affect on GSS.
The height of a font implicitly defines the width.
The GSS selection remains in effect until the next occurrence of GSS
in the data stream, reset, or power down. The height and width
selected may be further modified by Graphic Size Modification (GSM).
The GSS command can be used in die middle of a line without
affecting the alignment of characters along the baseline.
Side Effects
GSS sets GSM to 100;100.
The GSS command affects line spacing only when font-dependent
spacing is selected.
Notes to Software
If you are not using font-dependent spacing, or if you switch to taller
characters in the middle of a line, use Select Vertical Spacing (SVS) to
accommodate the change in character size.
